Need printer recommendation for D800E

Hi all! I've been using my D800E for almost 2 years and now feel the need to make some prints as a gift to friends/family and for myself. I'm completely a newbie when it comes to printing. I'd like to be able to print big enough, maybe up to a poster size, and with enough quality to honor the D800E's IQ. I'd appreciate your suggestions regarding printer,paper, software, etc. Thanks.
